' DAYTON, OHIO, A CORPORATION or DELAWARE REFRIGERATING APPARATUS Application filed ma 30,

This invention relates to refrigerating apparatus and more particularly to a refrigerator of the mechanical household type in which a cooling unit is mounted in a compartment of a cabinet. I

An object of this invention is to provide a cabinet and a cooling unit each provided with means for facilitating the installation of the cooling unit in the cabinet.

. 1 Another object of this invention is to provide means permitting the installation of a cooling unit in a refrigerator cabinet without danger of damaging the cabinet 01' the cooling unit.

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawing, wherein a preferred form of the present invention is clearly shown.

In the drawing:

Fig. 1 is a vertical cross-section of a portion of a refrigerator embodying features of my invention;

Fig. 2 is a horizontal cross-section taken along the line 2-2 of Fig. 1:

Fig. 3 is an enlarged detailed view in crosssection of the means for installing the cooling unit in the cabinet provided at the rear of the cooling unit; and

Fig. -t is a view similar to Fig. 3 showing the means used at the frontof the cooling unit.

A refrigerating apparatus. embodying features of my invention may comprise a cabinet generally designated as 20 .in which a cooling unit generally designated as 21 is installed. Any type of refrigerant may be used in this cooling unit and as an embodimentthereof the cooling unit may receive liquid SO through the. pipe 22 and the evaporated SO may leave the cooling unit through the pipe '23. These pipes 22 and may lead to any suitable refrigerant liquefying means, such as of the compressor-condenser type, which may 1928. Serial No. 281,604.

be installed either in the cabinet 20 or in any other convenient place.

The cabinet 20 may be provided with a lining generally designated as 2-1 around which any suitable installation 25 is adapted to be placed. An outer casing 26 may be provided for the cabinet. Suitable means for hanging the cooling unit in the cabinet may be provided. Such means may comprise a plurality of inwardly directed projections 21' and the cooling unit may be provided with suitable hanging means 28 adapted to cooperate with the inwardly directed projections 27 for installing the cooling unit in the cabinet.

The inwardly directed projections '27 may comprise bolts having heads 27awhich bolts may be passed through the lining 2%. Suitable metallic strips 29 may be placed on the outside of the lining 2-2 and may be spaced therefrom by gaskets 30 made of rubber or the like. The strips 29 may be provided with square or any other non-circ'ular hole 31 through which the bolts 27 may be passed. The bolts may be then secured in place by the use of a washer 3'2 of relatively large size and a small washer 33 which may be locked in place by a nut 34. The inwardly directed projections thus far described may be identical both at the front and the rear of the cooling unit. The rear projections may be provided with two plates 37 spaced by a sleeve 38 and these plates may be secured in place by a nut 39 before installation of the cooling unit.

The cooling unit at the rear may be provided with a hanger 40 which may be provided with horizontal tlat ends -11 and these flat ends may have notches 42 cut therein. These notches 42 are adapted to fit around the sleeve 38 of the rear inwardly directed projections 27. The front hanger l5 may have horizontal fiat ends 46 which are provided with notches -17. These notches 47 are directed in a different direction from notches '42.

After placing the notches 42 around the sleeve 38, suitable washers 48 may be placed on the ends 46 and the front hanger 45 together with the front end of the cooling unit may be slid upwardly with the notches 47 around inwardly directed projections 27. Suitable washers 49 may then be clamped underneath the ends 46 of the hanger by nuts 50 thus providing locking means for the front hanger 45. The hangers in general may comprise an upper U-shaped member 60 and a lower U-shaped member 61 continuing into Z brackets 28. These two members ma be clamped around suitable portions of the cooling unit 21.

In installing the cooling unit in the cabinet the rear hanger 40 is first tilted upwardly in the rear, and the rear hanger 40 is placed by sliding the notches 42 around the sleeves 38. The connection in the rear is thus a hooking or sliding connection. By the term sliding connection or hooking connection I mean a connection which may be made without the necessity of manipulating some locking means such as a nut or the like. The front end of the cooling unit is then lifted upwardl v with the notches 47 around the front projections 27 and then the front hanger 45 is locked in place by means of the washer 49 and the nuts 50. The front connection is thusalockingconnection. Bythe term locking connection I mean a connection in which a locking member, such as a nut or the like, is manipulated or disturbed after or while the cooling unit is placed in the cabinet. By this arrangement the practice heretofore prevailing of reaching around the coolingyunit in the cabinet with tools, such as wrenches, in order to turn the rear clamping nuts, while trying to support the unit in place, is eliminated. This prior practice often resulted in chipping the enamel with which the lining 24 is usually provided. The rear of the cooling unit was also a very inconvenient place to manipuluate the necessary tools and by my improved means this danger and inconvenience is eliminated.

As heretofore stated, the notches 47 and 42 are directed in different directions from one another. By arranging the notches in this manner the ends of the rear hanger may be slid or hooked in retaining position with their respective projections after which the ends of the front hanger are lifted vertically into engagement with their respective projections. By arranging the notches 47 and 42 in opposite directions, the notches 47 and the front projections 27 themselves prevent movement of the rear hanging means in an opposite direction when the front hahging members are in engagement with their respective projections. Thus it is apparent that the cooling unit is prevented from moving in any horizontal direction after being assembled and secured in the cabinet.

While the form of embodiment of the invention as herein disclosed, constitutes a preferred form, it is to be understood that other forms might be adopted, all coming within the scope of the claims which follow.

What is claimed is as follows:
